METHOD OF SEALING FOIL AND FOIL PACKAGE.

Application filed March 10, 1922.

To all whom it may concern Be it known that I, EDWIN J. CONLEY, acitizen. of the United States, a resident of New York, in the county ofNew York and State of New York. have invented a certain new and usefulMethod of Scaling Foil and Foil Package, of which the following is a.specification.

This invention involves a variation in the method of forming packages asdescribed in my previous Patent No.1,398,840, and one of its chiefcharacteristics is a method of sealing the package by fusing the foilindirectly, that is, by applying the scaling instrument not against thefoil itself but against paper or other similar material which covers thefoil.

The invention may be illustrated by numerous embodiments, and thefollowing descrhjJtion .is intended to represent three embodiments whichhave been found particularly advantageous and useful.

The accompanying drawings which form part of this specificationillustrate said embodiments. Figures 1 to 5 showing the first form ofpackage Figures 6 to 8 a second form, and Figures 9 to .16 a third form.

Figure 1 represents a section of a bag formed of foil and paper;

F ig. 2 re inresents a section taken at right angles to that of Fig. 1;

Fig. 3 represents the paper blank and the foil blank used for formingthe bag;

Fig. 1 represents these blanks folded over on the line 6, 11;

Fig. 5 represents the folded blanks shown in Fig. 4 folded on the sidesto complete the package;

Fig. 6 represents a section of a second form of bag;

Fig. 7 represents a section at right angles to that of Fig. 6;

Fig. 8 represents the foil and paper blanks used in making this secondform;

Fig. 9 represents a foil blank with paper underneath for making a thirdform of package;

Fig. 10 represents a section thereof on line 10---1O; l i

in the first operation of forming thev package;

r Fig. 12 represents a on line 12-12. I

F 13 represents the second and third operations in forming this packageconsisting in folding over the foil and paper at their edges. 7

Fig. 14 represents a section of Fig. 1 on line 14tl-it;

Fig. 15 represents the fourth step in formmg the package;

Fig. 16 represents a section of Fig. 15 on line 16-16; and

Fig. 17 represents the package completed at one end thereof.

On the various figures of the drawings, the letter P designates paper orsimilar material; F designates foil; P. folded p01- tions of the paper;and F folded portions of the foil. 7

In the illustrations of. the invention of my said previous patent whichare described therein, the foil is fused together bythe application of asuitably heated surface directly to the foil. l have discovered thatoverlapping portions of foil. and particw larly relatively thin foil.that is. foil. than 3/1000 of an inch in thickness, can be section ofFig. 11

fused together when they are covered by paper by the application of heatto the surface of the paper and its con'imunication to the foil throughthe paper without injuring or destipyinsz the paper. This surprisingfact makes it possible to fuse together the foil of a package where thefoil is covered by paper, or other similar material, after the packageor wrapper has been partly or wholly assembled. This reduces the numberof operations required to make the package or receptacle and alsoreduces the danger of injury of the foil by direct contact of theheating surface with the foil, especially Where there is any danger ofmovement of the heating surface across the surface of the foil. I 7

With reference first to Figs. 1 to 5, there is shown a sheet of foil inthe form of a rectangle 1, 2, 3, 4 which is placed upon a sheet of paperout to form an irregular- 1 ,esseoo shaped piece denoted and defined bythe numerals 5, 6, 7, 8, 9, 10, ll, 12. lit will be seen that this sheetof paper is wider than the foil sheet in the upper portion andcorrespondingly narrower in the lower portion, these portions beingdefined by a median line 6, 11. When these superimposed sheets arefolded over at said line 6, ll shown by Fig. l so as to bring foil incontact with foil, there will result a folded toil sheet de noted by therectangle 1, 2, i l, 13, and the upper portion of t is folded papersheet will obviously occupy the rectangle 15, 16, 10, 7. The nextoperation consists in making a fold along line'l'i", 1.8 and line 19,20. and then bringing the edge or" the foil 1. 13 over into position 15,7 with th edge of the paper 5. 6.

into position 21, 522. The other side is tolded in the same manner. Theedges 5, 6 and 11., 12 of the paper are sealed in some suitable way asby gluing them to the body of the package. The finished package is shownin Fig. 5.

There is thus provided a package which is folded in such a manner as tobring; the edges of the foil in ipping relation to provide i ourthicknesses. as clearly shown in Fig. in which the paper portions are onthe outside as denoted by the letters 7? and the foil portions are onthe inside as denoted by the letters ll. The overlapping; foilportions-are shown at F and the overlapping paper portioi'is at P. henthe package is thus formed, a sealing; instrument heated to the propertemperature as described in my aforesaid Patent l .ZlllSJJ-lt). is

applied to the paper surface on boh sides of the package acbacent the:lolds l!" with the result that these toil tolos are sealed by fusion,the heat being conducted through the paper and there being no directcontact between the sealing' instrument and the toil. No flux or solderneed be used. A very secure hermetic seal is thus provided O'Wlllif tothe fusion and to the fact that the edges overlap. The overlapping flapsoi? paper at P may be sealed in any suitable way to the under yingpaper. as. for instance by gluin them.

In Figs. 6, 7. and 8, a second. embodiment of the invention shown. andthis is also in the form of a bag. This is termed tron'i a sheet of foildenoted by 1,3, 2 i, 25, 26 and an irregular sheet of paper denoted by7217. 29 80, 31., 26. These sheets are folded on. line 32-, 29'with thefoil against foil, so as to bring line '25, over 'onto'lin'e There is nooverlapping of the foil. eco this embodiment. The extendin paper flapsare suitably folded or i and sealed to the paper so that their edgeswill occupy the resulting positions Stand 85. 36. After this step thefusion of the toil brought about by applyin a heatedlsealing instrumentalong co tactingedges, as,

for example. along that portion of the paper denoted by the rectangle35. 86, 29, 9A and rectangle 28, 2d, 8d, 33.

The operation may be varied by per forming the fusion of the foil andthen sealing the paper flaps. but in this case also the fusing;o'peration r-Jould prel'eraiol be conducted by applying the sealinginstrument directly against the paper. The paper blank may of course becut in some other way. pro rided extending flaps suitably enclose thetoil.

While this method of scaling :toil. pact; ages has been set forth asapplied to base, it is to be pointed out that it may be also applied toboxes and other packag; s having); yielding or rigid contents. and infact it of general application wherever it is desired to seal a foilpackage which has already been enclosed in paper. whether or not thepaper has been finally sealed about the foil package. During the usingoperation the paper need not be injured by the heat owinp to the lowtennqeraturo that suliiccs for the fusing of the foil.

A. third embodiment of ti 2 invention is shown in Figs. 9 to 17. The pa.their in illiiistrated is made from slice of. :i'oil and paper oi? thesame .8 shown in l ie'. 9, and these sheets are tolded over on line Ill-3S as illustrated in ii and 1L. the foil being folded to provide anextending edge. The paper may be attached. to the foil in any suitablemanner. as. tor example. by gluing at points and ac. fi hter he roll andpaper have been lolded as it] Fu s. l1 and 12. the extending edgge oithe roll is haldcd around the other ed 'e as shown in Fig 13 and 141;.and extents o; edge oi? the paper is brought around *ith it to occupy;the position shown in section in lli lei.

he final step oi folding has been pertormal as shown in Figs-15 and 16by sealing down the remainin extending edge or flap oil the paper. Theoverlapping portions of the foil may now be sealed together by fusingthem with a heated sealing}; instrument applied to the paper whichencloses the foil.

Either end of the package may now be folded on lines such as 41 or 412and the corners may be bent over as shown at t? and a l: to provide amore comps at package. These corners in ay be sealed in any suitablemanner. Fig. 17 shows the completed. pa ole age except that the one endhas not been sealed since it is necessary to lea e it open for theintroduction of the articles to be e. closed therein. This particularpackage is adapted for containing one or more cigars. and after thesehave been introduced the open end may be sealed in an Y suitable manner. There is a distinct advantage in using thi's package forenclosingcigars since the foil retains the cigars in their originalconditi'ointhat is, it prevents the entrance of 1 ,433,soo

moisture, vapors. and odors. and furthermore prevents the loss of aromaor moisture from the cigar itself. The foil is preferably very thin andneither adds appreciably to the weight of the package nor to the cost ofmanufacture. The fusion of the foil provides a very good hermetic seal.

By the term relatively thin foil in this specification, I mean a foilhaving a thickneSs less than 3/1000 of an inch.

.\s many apparently widely different embodiments of this invention maybe made Without departing from the spirit thereof, it is to beunderstood that I do not intend to limit myself to the specificembodiment thereof, except as indicated in. the appended claims.

l surface fusion as occurring in the claims meant fusion by applyingheat and pressure to the surfaces of overlapping portions of foil. asdistinguished. from heat applied to the edges of the foil.
